BOX.

Appllcatlon filed April 26, 1927, Serial No. 186,687, and in Hungary June 5, 1926.

This invention relates to boxes of the type used as containers for shoe polish, and more particularly for boxes of such type in which the lid is not frictionally secured, but the 5 turned-down flange of the lid is provided with means engaging, in the closing position, a circular groove in the body of the box.

The object of. the invention is to provide a box as above specified which will be simple in construction and adapted to be manufactured of the same material as, and at inconsiderabl higher costs than, the ordinary boxes with. frictionally secured lid. Further objects of the invention are to facilitate the 1 opening and closing of the box and to obtain tight closure without the use of a packing.

According to the invention, the means engaging the circular groove are produced by providing the turned-down flange of the lid at two opposite portions of its circumference with narrow recesses so as to form internal feathers fitting into the groove of the body and catching therewith in the closing position. The internal feathers of the lid thus cooperate with the groove of the body to positively lock the lid against lifting from its closing position. When putting on the lid, and before the feathers catch with the groove, the flange of the lid is, of course, obliged to widen elastically at the recessed portions which widening involves a corresponding contraction transversely to the direction of widening. In order to eliminate any hindrance which the body of the box might offer to such contraction, such portions of the flange as partake in the contraction may be bent outwards so that, on the periphery of the flange, there appear two bosses staggered by 90 in relation to the recesses. It follows from the above-mentioned deformations to which the flange is subjected when the lid is put on, that the feathers are re leased from the groove by pressure at the bosses in the flange.

A flange with the said recesses and bosses afl'ords, of course, no tight closure. According to the invention, tight closure is nevertheless obtained by forming the flange cylindrically at that portion or zone only which comprises the recesses and bosses and making the portion or zone joining to the top late with a conical taper, the edge of the dy being formed with a taper preferaby of the same conicality and the circular groove being so distanced from the conical surface on the body in relation to the distance of the feathers from the conical surface on the lid that when the feathers catch with the groove the cone of the lid is tightly pressed on to the cone of the body, the reaction of the latter against compression being overcome by the locking enga ement of the feathers with the groove, but becoming efi'ective and causing the lid to be thrown off as soon as the feathers are released from the groove by lateral. pressure applied against the lid flange between its recessed portions.

A constructional form of the invention is shown, by way offlexample, in the accompanying drawings in which- Figs. 1 and 2 are two central sections at right angles of a closed box, and Fig. 3 is a plan View from below of the lid alone. The flange a of the lid A is formed only In the lower half cylindrically, while the upper half tapers in a conical surface 0 towards the top plate 6. Two opposite portions of the cylindrical zone are impressed with narrow recesses d, (P extending in circumferential direction to a fraction less than a quarter of the periphery-. Moreover, the cylindrical portion is formed with two bosses e, e staggered in circumferential direction by 90 in relation to the recesses.

The body B has a tapering edge f with 85 the conicality of the upper zone 0 of the flange a. The well known circular groove of the of the body B is so distanced from t e conical surface f that when 'the internal feathers formed by the recesses cl, d catch with the groove 9 the cone f is pressed into the cone 0 to secure tight closure.

What I laim is A box 0 the type described, consisting of a body having a circular groove on its side 05 and a tapering edge, in combination with a lid having a turned-down flange comprising a tapering upper zone adapted to receive said tapering edge of the body, and a cylindrical lower zone provided at opposite circumfer- 10o ential portions with narrow recesses forming tanced from said taperin edgethat by causinternal feathers adapted to catch with said ing said feathers to catc with said ve groove in the closing position of the lid and said tapering zone of the lid is force on to l positively lock said lid against lifting, but said tapering edge of the body.
